This invention has for its object to provide a writing nib particularlyfor use in a reservoir pen, which nib shall resemble .or bear theappearance of and also function in the same manner as the customary goldnibs, yet may be more cheaply produced than the existing nibs, and, inaddition, shall be as sensitive, stronger and more durable and reliablethan the known nibs.

Writing nibs of the kind usually applied to better class fountain pensare usually made wholly of gold and are therefore expensive to produce,whilst cheaper grade reservoir pens are generally fitted with nibs ofnon-precious or base metal which are neither as serviceable nor asdurable as gold nibs.

Under my invention, I provide a writing nib which combines cheapness ofproduction with the durability, smoothness, desired flexibility anddistinctiveness .of the customary gold nibs, and which nib is alsocapable of being readily applied to a pen or pen holder and positivelyheld in position in the usual manner of known types of writing nibs.

A writing nib, according to my invention, is composed of two sections.or components, namely a shank portion made of non-precious metal and a.writing point section made of precious metal, and in which nib theedges of the writing point section are bent or clipped over to formguides or passages for the reception of corresponding edges of. theshank portion; or, conversely, the edges of the shank portion are bentor clipped .over to form guides or passages for the reception ofcorresponding edges of the writing point section.

Thus the composite nib, when applied to a pen or pen holder, resemblesthe usual costly nib but includes in its construction only a minimum ofprecious metal.

I will further describe my invention with the aid of the accompanyingsheet of explanatory drawings which illustrate, by way of example only,one mode of carrying the same into effect.

In said drawings:-

Figs. 1 and 2 are plan views and Figs. 3 and 4 are side views ofcomponents of a two part nib the two components being separated. Fig. 5is a front view of one part of the nib.

Figs. 6 and 7 illustrate, in plan and side view respectively, thecomplete nib.

A shank component or element a of the nib is of non-precious or basemetal and is provided (Cl. 120-109) F at or about the middle with a slota and adjacent to said slot there are preferably formed an aperture aand a longitudinal recess or groove (1 communicating therewith. Alongitudinal slot a leads to and terminates at the forward end 5 of theshank a which is preferably of semi-circular configuration and hasoutwardly extending shoulders a The point component b which is gold orother precious metal, is tapered or. shaped in the usual manner toprovide wings 10 or prongs b (which may be tipped with iridium or thelike) having between them the slit b which extends lengthwise in arearward direction towards and terminates in an aperture 1) formed in anintermediate part of the section, such 00- operating slits and aperture(1 12 b and aperture a and recess a of the respective shank and pointelements combining to form efiicient feed channels for the passage ofink to'the tip of the writing point b.

The writing point section, which is made slightly wider than the shankportion a, is so shaped or bent at its respective edge portions as tocreate a longitudinally-formed guide or passage 0, and into said guidethe shank portion a is clipped or inserted, whilst the rear of the pointsection b tapers from its opposed edges in a rearward direction tocreate at the rear end a tongue or projection d which is entered in saidslot a of the shank section a in order to position the point sectionupon the shank.

In a modified construction, said shank component may be provided withlongitudinal guides or passages adapted to be bent or clipped over thecorresponding edge portions of the point sec- 3 tion.

What I claim as my invention and desire to secure by Letters Patent is:-

A writing nib composed of two sections namely a shank portion made ofnon-precious metal and a writing point section made of precious a metal,and in which nib the edges of the writing point section are clipped overto form guides for the reception of corresponding edges of the shankportion, said shank and writing point sections being provided withco-operating slits and apertures combining to form ink feed channels tothe tip of the writing point, and the writing point section ispositioned by a projection formed on the rear end of the point sectionwhich engages an aperture formed in the shank portion.
